Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles
Answer:
x = 10
Step-by-step explanation:
l n 20 + l n 5 = 2 l n x
ln (20×5) = ln x²
ln(100) = lnx²
100 = x²
x = +/- 10
Since logs of negative numebrs don't exist, we reject -10
A four sided polygon, 4 edges and 4 corners
Answer:
5 / 6
Step-by-step explanation:
The green numbers: 1, 2, 5
The even numbers: 2, 4, 6
Since 2 is an overlap, we'll only count it once.
Total outcomes: 6
Successful outcomes: 5
Probability: 5 / 6
